2.1 Operating Principle

The machine works on the claw principle.

Transport | 3

0870159870_MV1202A_A0001_IM_en 5 / 20

2.2 ApplicationThe machine is intended for the suction of air and other dry, non-aggressive, non-toxicand non-explosive gases.

Conveying of other media leads to an increased thermal and/or mechanical load on themachine and is permissible only after a consultation with Busch.

The machine is intended for the placement in a non-potentially explosive environment.

The machine is suitable for continuous operation.

Permitted environmental conditions see Technical Data [} 18].

2.3 Standard Features

2.3.1 Vacuum Relief ValveThe ultimate pressure is limited by a vacuum relief valve. The vacuum relief valve is ad-justed ex-works to the minimum permitted ultimate pressure (see nameplate).

2.4 Optional Accessories

2.4.1 Inlet FilterIt protects the machine against dust and other solids in the process gas. The inlet filter isavailable with a paper or polyester cartridge.

3 Transport

WARNINGSuspended load.

Risk of severe injury!

• Do not walk, stand or work under suspended loads.

6 / 20 0870159870_MV1202A_A0001_IM_en

• Check the machine for transport damage.

In case of the machine being secured to a base plate:

• Remove the fixations.

WARNINGLifting the machine using the motor eye bolt.

Risk of severe injury!

• Do not lift the machine using the eye bolt fitted to the motor. Only lift the machine aspreviously shown.

4 Storage• Seal all apertures with adhesive tape or reuse provided caps.

In case of storage of more than 3 months is scheduled:

• Wrap the machine in a corrosion inhibiting film.

• Store the machine indoors, dry, dust free and if possible in original packagingpreferably at temperatures between 0 ... 40 °C.

~1 m

• Make sure that the environment of the machine is not potentially explosive.

• Make sure that the ambient conditions comply with the Technical Data [} 18].• Make sure that the environmental conditions comply with the protection class of the

motor.

• Make sure that the installation space or location is vented such that sufficient coolingof the machine is provided.

• Make sure that cooling air inlets and outlets are not covered or obstructed and thatthe cooling air flow is not affected adversely in any other way.

Installation | 5

0870159870_MV1202A_A0001_IM_en 7 / 20

• Make sure that the oil sight glass (OSG) remains easily visible.

• Make sure that enough space remains for maintenance work.

• Make sure that the machine is placed or mounted horizontally, a maximum of 1° inany direction.

• Check the oil level, see Oil Level Inspection [} 11].• Make sure that all provided covers, guards, hoods, etc. are mounted.

5.2 Connecting Lines / Pipes• Make sure that the connection lines cause no stress on the machine‘s connection, if

necessary use flexible joints.

• Make sure that the line size of the connection lines over the entire length is at least aslarge as the connections of the machine.

In case of very long connection lines it is advisable to use larger line sizes in order toavoid a loss of efficiency. Seek advice from your Busch representative.

5.2.1 Suction Connection

NOTICEIntruding foreign objects or liquids.

Risk of damage to the machine!

In case of the inlet gas contains dust or other foreign solid particles:

• Install a suitable filter (5 micron or less) upstream the machine.

Connection size:

– DN100 PN10/16

Depending on the specific order, other connection dimensions may apply.

5.2.2 Discharge ConnectionConnection size:

– DN100 PN10/16

Depending on the specific order, other connection dimensions may apply.

• Make sure that the discharged gas will flow without obstruction. Do not shut off orthrottle the discharge line or use it as a pressurised air source.

Unless the aspirated air is discharged to the environment right at the machine:

• Make sure that the discharge line either slopes away from the machine or provide a li-quid separator or a siphon with a drain cock, so that no liquids can flow back into themachine.

5.3 Filling OilThe oil level should stay constant over the lifetime of the oil. If the level does fall, thegear is leaky and the machine requires repair.

Risk of electrical shock.

• Electrical installation work must only be executed by qualified personnel.

• Make sure that the power supply for the motor is compatible with the data on thenameplate of the motor.

• Provide an overload protection according to EN 60204-1 for the motor.

• Connect the protective earth conductor.

• Electrically connect the motor.

NOTICEIncorrect connection.

Risk of damage to the motor!

• The wiring diagrams given below are typical. Check the inside of the terminal box formotor connection instructions/diagrams.

NOTICEIncorrect direction of rotation.

Risk of damage to the motor!

• Operation in the wrong direction of rotation can destroy the machine in a short time!Prior to starting-up make sure that the machine is operated in the right direction.

• Determine the intended direction of rotation with the arrow (stuck on or cast).

• Jog the motor briefly.

If the rotation must be changed:

• Switch any two of the motor phase wires.

6 Commissioning

NOTICELubricating a dry running machine (process chamber).

Risk of damage to the machine!

• Do not lubricate the process chamber of the machine with oil or grease.

CAUTIONDuring operation the surface of the machine may reach temperatures of more than70°C.

Risk of burns!

• Avoid contact with the machine during and directly after operation.

CAUTIONNoise of running machine.

Risk of damage to hearing!

If persons are present in the vicinity of a non noise insulated machine over extendedperiods:

• Make sure that ear protection is being used.

• Make sure that the installation conditions (see Installation Conditions [} 6]) are com-plied with.

• Switch on the machine.

• Make sure that the maximum permissible number of starts does not exceed 12 startsper hour.

As soon as the machine is operated under normal operating conditions:

• Measure the motor current and record it as reference for future maintenance andtroubleshooting work.

6.1 Conveying Condensable VapoursWater vapour within the gas flow is tolerated within certain limits. The conveyance ofother vapours shall be agreed upon with Busch.

In order to use the machine for the conveyance of condensable vapours, the machinemust be equipped with a corrosion protection coating (Aqua version) and a drain cock inthe silencer.

If condensable vapours are to be conveyed:

Before process:

• Warm up the machine for approximately half an hour.

After process:

• Operate the machine for approximately another half an hour.

• Regularly drain condensate from the silencer with the drain cock.

7 Maintenance

WARNINGMachines contaminated with hazardous material.

Risk of poisoning!

Risk of infection!

If the machine is contaminated with hazardous material:

• Wear appropriate personal protective equipment.

CAUTIONHot surface.

Risk of burns!

• Prior to any action requiring touching the machine, let the machine cool down first.

• Shut down the machine and lock against inadvertent start up.

• Vent the connected lines to atmospheric pressure.

If necessary:

• Disconnect all connections.

7.1 Maintenance ScheduleThe maintenance intervals depend very much on the individual operating conditions. Theintervals given below are desired to be considered as starting values which should beshortened or extended as appropriate. Particularly heavy duty operation, such as highdust loads in the environment or in the process gas, other contamination or ingress ofprocess material, can make it necessary to shorten the maintenance intervals significant-ly.Monthly In case of an inlet filter being installed:

• Check the inlet filter cartridge, replace if neces-sary.

Every 3 months • Check the oil level, see Oil Level Inspection [} 11].Every 6 months • Clean the machine from dust and dirt.

Every 20000 hours • Change the oil.

The change interval of 20000 operating hours is validfor Busch approved oils only. The change interval de-pends very much on the operating conditions. Border-line operation may reduce the change interval down toapproximately 5000 operating hours. Other oils may re-duce the change interval.

Every 6 years • Have a major overhaul on the machine (contactBusch).

7.2 Oil Level Inspection• Shut down the machine.

• When the machine is stopped, wait 1 minute before checking the oil level.
